The Mars rovers Spirit and Opportunity have gone over and beyond everybody's expectations from the original planned mission of several months to what became a mission of over eight-years...and counting!
NASA is prepping their next generation rover, the Curiosity. This new Rover is the larger in scale, about the size of a Volkwagon and is currently undergoing tests at NASA's Jet Propulsion Laboratory in Pasedena, CA. If testing goes well, Curiosity is set to launch anytime between November 25th and December 18th of 2011...
The mission will use Curiosity to study one of the most intriguing places on Mars -- still to be selected from among four finalist landing-site candidates. It will study whether a selected area of Mars has offered environmental conditions favorable for microbial life and for preserving evidence about whether Martian life has existed.
